punktfunk/packaging/windows/punktfunk-host.iss

; punktfunk host installer (Inno Setup 6).
;
; Produces a signed setup.exe that lays the host into Program Files, optionally installs the bundled
; SudoVDA virtual-display driver, and DELEGATES service registration to `punktfunk-host service
; install`. The real, idempotent install logic (SCM registration, firewall rules, default host.env,
; the SYSTEM→interactive-session CreateProcessAsUserW supervisor for secure-desktop capture) lives in
; crates/punktfunk-host/src/service.rs — this script does NOT duplicate it. That SYSTEM service model
; is exactly why MSIX is unusable here and we ship a classic elevated installer instead.
;
; Built by pack-host-installer.ps1, e.g.:
;   ISCC.exe /DMyAppVersion=0.2.123 /DBinDir=C:\t\release /DStageDir=C:\t\out\stage \
;            /DOutputDir=C:\t\out packaging\windows\punktfunk-host.iss
; Omit /DStageDir to build an installer WITHOUT the bundled driver (driver becomes a prerequisite).

  the OLD binary), so stop it and WAIT for STOPPED before files are copied. Best-effort; a fresh
  install is a no-op (the service doesn't exist yet). }
